Estimates were attenuated, but remained statistically significant, when adjusting for NT-proBNP in sensitivity model A (AF; HR: 1.20, 95% CI: 1.07–1.33, P = 0.0013 and HF; HR: 1.45, 95% CI: 1.26–1.68, P < 0.001) and inflammation markers in sensitivity model B (AF; HR: 1.59, 95% CI: 1.41–1.80, P < 0.001 and HF; HR: 1.51, 95% CI: 1.29–1.77, P < 0.001). This evidence concerns the gene NPPB and hydrops fetalis.
